肺硬化性血管瘤的CT诊断

目的探讨肺硬化性血管瘤（PSH）的CT影像特点及诊断价值。方法回顾性分析经手术病理证实的10例PSH患者的胸部CT平扫及增强扫描资料。结果 10例PSH中,位于右肺6例、位于左肺4例,全部为单发结节灶。CT平扫病变呈圆形或类圆形,边界光滑锐利6个,边界不光滑4个;密度均匀8个,不均匀2个。其中空气新月征2例,瘤周磨玻璃样影3例,贴边血管征3例,邻近的右肺动脉扩张增粗1例。增强扫描病灶均匀强化7例,不均匀强化3例。结论境界清晰、密度均匀、明显强化为PSH的主要表现,综合分析其他征象有益于提高诊断准确率。

The value of CT in diagnosis of pulmonary sclerosing hemangioma

Objective To analyze the imaging findings of pulmonary sclerosing hemangioma（PSH）and to improve the diagnosis and differential diagnosis of the PSH.Methods The imaging findings of 10 cases of PSH confirmed by pathology were analyzed retrospectively.All cases underwent CT plain scanning and contrast enhancement CT scans.Results All cases were solitary,on precontrast enhanced CT imaging,well-defined round or oval lesions were shown in 6lesions,4cases had ill defined margins.Eight lesions were homogeneous,while,2lesions were heterogeneous.Characteristic air meniscus sign（n=2）,vessels at its periphery（n=3）,ground glass around the lesion in 3cases,and prominent pulmonary artery sign（n=1）were shown.Seven lesions were enhanced homogeneously and 3lesions enhanced heterogeneously among ten lesions.Conclusion Well-defined and homogeneous masses with marked continuing enhancement are the main findings of PSH.Comprehensive analysis of all the signs will help to improve diagnosis.
